vn v6 to v8 brakes

[millaz88]

hey sorry if this is already posted but i was just wondering what would be more worth it im thinkin about gettin some slotted rotors but have seen that the v8 front rotors are bigged for how do i go about fittin v8 rotors and calipers? do i need v8 struts or are they the same and also is it really that much of a differane im not racin it just street use mainly to from work

simple bolt on can find v8 style calipers on series 2 vp commodores. They have Finned calipers.witha bigger master cylinder from a v8 it will make a bit of difference

agreed on the discs and calipers, but i don't think the VP S2 has a bigger master cylinder, i just pulled mine and it was 15/16. i'm swapping it for a v8 one (1" MC and bigger booster)

^^^ wot he says. If you don't change the master cyl too the pedal travel will be too long and have a spongy(er) pedal.

Well the VN S-packs had the VN V8 brakes.

Consisting of:

1.) Dual/Double Brake Booster rather than Single

2.) 1" Master Cylinder rather than 15/16

3.) Bigger & Finned FRONT brake calipers - rear brake calipers same as on V6


You can just swap the V6 VN front calipers for V8 ones. In theory they would perform better in high-stress situations where the brakes often run hot for example. But then again using Bendix brake pads on V6 brakes largely solves this problem anyway.

If your brakes overheat often then the bigger calipers would be ideal, along with Bendix pads.

Really, the V6 brakes with a properly bled brake system and Bendix pads should be great for a road car.


VP S2 didn't have a bigger master cylinder nor a bigger brake booster.

The double booster makes a big difference if you have an extra-heavy car etc, but is more worthwhile with the bigger calipers. The master cylinder isn't as important in my experience, again if the system is properly bled with good pads.

Forgot to mention - you can't fit 14" wheels onto the front of a car with the V8 brakes. That's why VP S2 had 15" wheels rather than 14".

Hint: VR onwards commodores also have "v8 brakes" but some are fitted with a 15/16th master cylinder.

as said above, they will bolt straight on to the v6 strut.

Diffrences?
v8 has
1" master cylinder
290mm ventilated rotors (front)
Finned callipers (same brake pads as the v6 callipers)

i didn't notice a big difference. it only makes a real difference with repeat breaking.

Rear brakes are no different V6 to v8

alright so i just got of the phone to the wreakers n they said for vp $55 per strut $33 per dic n $33 per caliper so im thinkin about just changen the hole lot over this will just bolt up right p.s gettin the hole lot as my front struts a bent needed new ones for roadworthy anyways

VN and VS rotors are totally different. You need to change the hub for VS ones to fit in which case you may as well get a VT kit and do the job properly.
